Katherine, pictured here with Arnold Schwarzenegger in Los Angeles on August 8, says she has a new addiction to singer Adele’s emotional lyrics — and shopping. She tells the magazine, “I’m like, retail therapy all the way.”

On her mother, Maria Shriver:

“I’ve always been way closer to my mom. Even when I was little, I was glued to her all the time. I’m close to my dad, but they’re totally different kinds of relationships,” Katherine said.

“I talk to my mom about six times a day, and we constantly e-mail in between that. People say that I’m her twin. I guess it would be the Kennedy genes; my cheekbones are coming out. We’ll be at the breakfast table and my mom will look over at me and say, ‘I see them!'”

Living with the Schwarzenegger name:

“I thought of changing it because, especially for dating, it’s impossible,” Katherine said. “It’s something I deal with every day, and I am hyperconscious about it. When I got to college, people — much more guys than girls because girls don’t give a crap about bodybuilding — were coming up to me, and it would automatically jump to a conversation about my dad and weight lifting or how to do a proper bicep curl. It’s like, ‘Do you want to date my father, or do you want to date me? Like, I can arrange that for you.'”

Who’s been ‘so inappropriate’ during the split:

“Me and my siblings have never really been in the spotlight growing up,” Katherine revealed. “My parents always really sheltered us, so when [the separation] started happening, it was like everything came out of nowhere overnight.

I would go out to lunch, and literally 20 people would come and scream at me. And I’m like, ‘This is so inappropriate; you’re trying to provoke me to have an attack and say something crazy.'”

She believes Everything happens for a reason:

“I really do believe everything happens for a reason,” Katherine said. “A lot of the time, it’s hard to understand in the moment why things are happening, but I really do think that. I also like to think God doesn’t really give you anything you can’t handle.”
